Title: Elevator platform door closure detecting device
Inventor: TAKAHASHI TATSUJI
IPC: B66B13/22
Filed: 1989-12-28
Abstract: PURPOSE:To exactly transmit signals of door-closing and locking to a control circuit when a platform door is closed by forming the width of a contact blade at the connecting position slightly wider than the width of a short-circuit contact. CONSTITUTION:The width between 6a and 6b of a short-circuit contact 6 connected with a contact blade at the tip part of the contact blade 7 made of insulating material, is formed to be B-2d, that is, so as to be slightly narrower than the width B between 7a and 7b. As a result, for example, even when a combined body of the short-circuit contact 6 with the contact blade 7 is attached to a latch 8 while it is bent, the contact blade 7 contacts a mounting metal plate 4, but there is no fear of contact of the short-circuit contact 6 with the mounting metal plate 4. Even when a platform door is operated while it is tilted under the influence of impact, etc., contact of the short-circuit contact 6 with the mounting metal plate 4 is thus prevented. Thus, the leakage of current of a detection circuit to the mounting metal plate 4, etc., during closing of the platform door does not occur, and exact detection signals can be transmitted to a control circuit.

Filed: 1994-12-30
Abstract: PURPOSE: To print beautifully in good balance within printing frames by installing a printing control part etc., for printing with a printer in the conditions of the optimum registered character size and intercharacter space. CONSTITUTION: Printing width is inputted using a button switch and a display. The inputted current value is compared with an inputted set value to judge whether the current value is within the range of the set value. If it is necessary to enlarge a font, the rank of fonts is enlarged from the current value, and the optimum font is selected from fonts X1-X5. When printing width is judged to exceed a set value, an intercharacter space (dot space) is inserted, and the width size of printing with the intercharacter space inserted is calculated. The calculated width is compared with an inputted set value. When the calculated width is judged to exceed the set value, the inserted intercharacter space is deleted for one time, and the optimum intercharacter space is determined to finish the process.

Title: Optical recording medium and its reproducing method
Inventor: TSUJIOKA TSUYOSHI
IPC: G11B7/24035
Filed: 1989-12-27
Abstract: PURPOSE:To enable multiple recording and reproducing of data by forming magnetic layers so that any material in the magnetic layer has different intrinsic value of the angle of optical rotation from others or any combination of materials has different intrinsic values of the angle of optical rotation. CONSTITUTION:Recording layers 1 - 3 having different angle of optical rotation are formed on a transparent substrate 4. The angle of optical rotation of each layer is determined by the concn. of optical rotating material incorporated into the layer and by the thickness thereof. When a light beam irradiates the medium, the polarization plane of the beam is rotated according to the state of each material, each corresponding to the combination of recording state of the materials. Therefore, by detecting the angle of optical rotation of the polarization plane of transmitted light (or reflected light if the medium has a reflecting layer) from the medium, the recording state of each layer can be identified. Thereby, multiple recording/reproducing is possible with this medium by making use of optical rotatory power.
